Health Issues Designing Senior Environments
The needs of seniors are critical as provided by Philadelphia Corporation for Aging (PCA). This is because environment affects peopleââ¬â¢s behaviours, health, feelings and productivity. Designing senior environments process should consider human-environmental interactions. As such, it involves maintenance, protection and restoration of environments to promote proper behaviours and good health.Advertising We will write a custom essay sample on Health Issues: Designing Senior Environments specifically for you for only $16.05 $11/page Learn More In addition, the environment should suit a diverse range of seniors such as those with Alzheimerââ¬â¢s and physical disabilities (Boyer 58). Based on Philadelphia reports, it is essential to consider facilities that can address the rising needs of seniors in the society. Therefore, the facilities should offer seniors an ideal environment to live through enhancement of health and well-being. Seniors have diffe rent needs in urban areas like Philadelphia. Initially, it is necessary to understand that seniorsââ¬â¢ requirements are unique. In this case, seniors should have access to specific desires and spaces for social interactions. This implies that the environment should promote a sense of social relations between seniors and caregivers. Throuwgh this effort, seniors enjoy the convenience of a comfortable environment. Furthermore, the specifications of residential units are vital in maintaining safety of the seniors. Meanwhile, seniors desire to live in a serene environment. In this regard, seniors desire accessibility to natural daylight, attractive aesthetic colours, minimal noises and rough-textured floors. Such factors will enhance safety of the seniors, which boosts their health conditions (Cekic 63). It is important to improve the level of seniorsââ¬â¢ privacy and dignity within the facility. The facility should offer residents their own rooms. In addition, the rooms should b e installed with sinks, tubs, toilets and showers. On the other hand, spa-facilities should be included if they are feasible. This makes the facility Spartan, which serves the needs of the residents. Moreover, the residents feel a sense of privacy because of reduction in crowding. This is caused by the minimal interference of oneââ¬â¢s activities. At the same time, this simulates the nature of privacy witnessed in homes.Advertising Looking for essay on aging? Let's see if we can help you!

Unlike the traditional nursing homes with immense utilities, the facility should mimic the normal home setup. This is because seniors despise living in secluded institutions. Furthermore, the facility should not have large common dining rooms and living rooms. This implies that residents sh ould relate in the facility as neighbours compared to admitted patients. As a result, the facility in the urban area will consider economies of scale while offering homelike conditions (Boyer 152). It is vital to introduce cordial design concepts amongst seniors. This creates a feeling of being at home rather than an institution. The facility that hosts seniors should be attractive and conducive. It is essential to utilize creativity to provide a healthy and conducive environment. This involves the physical appearance of walls, floors and other utilities. In addition, the number of utilities within the facility influences the behaviour and health of seniors. Most seniors prefer additional dining rooms, spacious resting utilities, and safe floors (Cekic 96). In addition, the furniture within the facility should be convenient for use by all residents. The services offered within the facility should be diverse. In this case, seniors will have the flexibility to choose. Some of the elem ents within a facility that determines the level of care include the number of expertise available, programs used and other benefits directed to seniors. Additionally, the process of offering rentals and skilled care should incorporate technology because technology increases the flexibility of seniors to make choices. Moreover, there are technological facilities that can be used to monitor and provide basic services to seniors. This will promote the lifespan of residents since it reduces the level of restrictions. As the seniors get older, they desire to be offered nursing needs. In this regard, the facility should provide skilled care and nursing to both retirees and old-aged. This implies that the facility should provide adequate care for healthy and feeble seniors.Advertising We will write a custom essay sample on Health Issues: Designing Senior Environments specifically for you for only $16.05 $11/page Learn More Through this process, the feeble sen iors will not feel discarded once they are too old. Since they will not be discharged, they will get motivated to live without interference caused by change in environment. This is a security for their long-term care (Cooper and Barnes 96). Since the facility is to be developed around the park in Philadelphia, it implies that seniors will be able to continue with their normal lives because they can still contribute to the economic activities within their residence. In addition, it will prompt more seniors to move to the facility because they cannot drop their normal lives. Therefore, living in the facility will just be a change of lifestyle rather than a store where the old-aged are dumped. This will encourage them to participate in cultural activities, sports and social responsibilities. Consequently, it will boost their health and fitness making them active over a long period. The location of the facility within Philadelphia implies that seniors will be able to continue with their urban lifestyles. This will boost accessibility to social amenities. Since the urban area is densely populated, it implies that seniors will not feel secluded. As a result, they can live longer and feel comfortable in the facility (Cooper and Barnes 196). This will also add value because their relations can visit them conveniently. The seniorââ¬â¢s environment should incorporate issues of sustainability. This implies that the facility should be environmental-friendly. Therefore, green design concepts should be incorporated in maintaining the seniorsââ¬â¢ facility. Such concepts include energy and water conservation, efficient lighting, day lighting and gardens. In addition, the facility should be able to accommodate multiple utilities that address human needs. This implies that the facility should be spacious where meetings and conference can be organized. As such, the facility becomes reusable even if the venture becomes infeasible (FitzSimons et al. 148). The nature of spac ing in the organization and apartment layout contributes significantly to the lives of the seniors. Considering that seniors are feeble in the society and demand extra attention, a spacious facility will be important. In this regard, they will have maximum freedom to engage in any event.Advertising Looking for essay on aging? Let's see if we can help you! Get your first paper with 15% OFF Learn More This will promote their mental and physical strength. As such, it will minimise crowding. Through this act, they will have a quiet and conducive environment. As a result, they will interact with their counterparts and challenge one another. All these vital elements of the facility will influence positively their health and welfare. The specifications of the seniors differ considerably with those of the population as a whole caused by the difference in the physical strengths and health of individuals. In most cases, seniors are made up of retirees and the old-aged. Therefore, they do not have adequate strength to engage in active exercises. In addition, most seniors have health issues that have to be handled considerably. In this case, they have to be provided with special treatment, which widens their lifespan. As such, many issues have to be considered when offering services at their new homes. These new homes should offer essential facilities that consider their needs. An environm ent where the seniorsââ¬â¢ facility is located is different from where other populations can reside. The seniors already had their active life during the early period, and for that reason, they demand a serene environment with minimal disturbances. This nature of the environment should be quiet, friendly and spacious. Through such a system, they can interact, relax and participate in physical fitness exercises. All these factors contribute to longer lifespan and health of the seniors. The urban parks will contribute significantly to the lives of the seniors. Initially, the parks will serve as a relaxing point. In this case, they can interact with one another. Through this act, they will encourage and support one another. At the same time, they will not engage in strenuous activities as to affect their health. When the weather is favourable, parks offer an ideal environment to undertake physical exercises. These exercises will boost the conditions of their health. Notably, parks h ave a green environment that offers fresh air and room for other activities. In this case, they will be out of trouble caused by air pollutions when relaxing (FitzSimons et al. 157). Parks also offer additional area to visit during times of indoor boredom. In this case, seniors will feel comfortable due to the variety of places they can visit because the parks will offer additional homelike settings. Through this process, the individuals will improve the status of their health conditions. Similarly, spacious environment within the parks gives them a chance to participate in teamwork. In such incidence, they offer one another motivation through life experience. As a result, they will live longer while their welfare is catered. Another critical element about parks is the interaction that seniors have with other population members. Since the facility is going to be established close to a park, it implies that seniors will have a close relationship with other members of the society. In this regard, parks always group people from all works of life. In addition, it offers people the right to undertake their own activities. Through this act, the seniors will feel as part of the society. This will be enhanced by the frequent interactions they will have with other people. Moreover, they will be able to contribute back to the community through sharing experience of their childhood and early adulthood. In this case, they will be kept active and healthy for long (Gilster and Margarette 52). The assistance received from the neighbours at park plays a crucial role towards the lives of the seniors. When seniors are at the parks, they will interact with people from other age groups. In this scenario, they will be assisted on issues they do not understand. In addition, they can be provided with the necessary support and skilled care from third parties. This process will reduce the boredom caused by monotony within the residential. Consequently, their lives will be the centre o f everyone when they are aging. This will boost their level of significance in the society. Works Cited Boyer, M Christine.

Women behave ambitiously and aggressive Essay Example | Topics and Well Written Essays - 250 words
Women behave ambitiously and aggressive - Essay Example On the same note, Sandbergââ¬â¢s personal experience shows that women are equally competitive as their male counterparts (5). In this respect, women should capitalize on their ambitions and aggressive workplace behavior in ensuring that they run the world alongside men. Women are not viewed positively in the workplace because they have given in to the stereotype threats where they believe that they cannot be on equal levels with the men balancing family and work responsibilities and hence end up giving up. This is further reinforced by the fact that women who are ambitious to be leaders are discouraged, shamed and even called unfriendly names. All this contribute to crashing their ambitious dreams and they resign to working at the lower levels in any workplace and letting he men take the lead. Even though ambitious women are not viewed positively in every work environment, it is important for women not to give up. Fight for affirmative action and promotion of women rights has been vibrant over the last several decades, an observation that occasions women to remain positive over their ambitions (Fels 120). In todayââ¬â¢s society, there are many women CEOs than ever recorded in history. In addition, Shafer (72) contends that women have increasingly taken up political leadership positions around the world. This shows that being ambitious and aggressive is positive, and women should allow the world to transition to this contemporary reality. If women perceive their ambitions to be positive, the global population will follow the same

An Analysis of Data On Rape Crimes
An Analysis of Data On Rape Crimes Introduction I will comment on the value of data and highlight advantages and disadvantages of this data and finally and come up with appropriate business actions that could be taken and enable Russex constabulary to help prioritise their work. Methods of data collection Official statistics are those published by the central Government. This source of statistical information informs the general public about the extent of notifiable offences. Official statistics are easy and cheap to access as you can observe them on the Home Office web page. The second source of statistical information comes from the British Crime Survey (BCS). These statistics are unofficial and the procedures used to gather information are completely different to the first, as the statistical data comes from surveys carried out by the public themselves. The statistics given are based on a large representative sample of the general public about their experiences as victims of household and personal crime. The BCS endeavours to provide a count of crime that consists of episodes not reported to the police, therefore examining the dark figure of crime which is not recorded in official statistics. The British Crime Survey (BCS) is a large random survey of private households, designed to give a count of crime that includes incidents not reported to the police, or those reported to them but not recorded. The main BCS interview takes place face-to-face, with no gender matching of interviewer and respondent. This context is not conducive to accurately measuring levels of highly personal victimisation. Estimates of the level of sexual victimisation obtained by the main BCS are acknowledged to be underestimates Consequently, the survey now makes use of Computer Assisted Self-Interviewing (CASI), whereby respondents keyed their responses into a laptop computer themselves. This method provides respondents with an increased sense of confidentiality and minimises interviewer effects. Respondents who answered the self-completion modules were routed through a series of three screener questions, designed to identify whether or not they had been a victim of a sexual offence. If they responded positively to one or more of these, they then answered a series of follow-up questions, designed to elicit the exact nature of the last incident experienced. Data as a management tool Data collection is practical because you cannot manage what you do not measure. Statistics from data enables a police department to make smart judgments and assists them in possibly identifying department and procedural problems. Data collection is also a great gesture to the community, showing law enforcement has the willingness to take an inward look to prevent discrimination. It also displays a true commitment by law enforcement to address community concerns and needs. Data collection gives everyone something to work with even though it might be just a partial solution. With mandatory data collection, officers will be forced to think about what happens during an encounter and what they do and say and possibly what parts should be looked at closer. Data collection provide a basis for important policy changes. Statistical techniques Line Graph A line graph is most useful in displaying data or information that changes continuously over time. The example below shows the Rape of a female from 1993-2005/06 Some of the strengths of line graphs are that: They are good at showing specific values of data, meaning that given one variable the other can easily be determined. They show trends in data clearly, meaning that they visibly show how one variable is affected by the other as it increases or decreases. They enable the viewer to make predictions about the results of data not yet recorded. Unfortunately, it is possible to alter the way a line graph appears to make data look a certain way. This is done by either not using consistent scales on the axes, meaning that the value in between each point along the axis may not be the same, or when comparing two graphs using different scales for each. It is important that we all be aware of how graphs can be made to look a certain way, when that might not be the way the data really is. Rape of a female Long-term national recorded crime trend he rate of rapes on females during this period has dramatically increased (see above). Leah Williams from the Womens Resource Centre stated that there were 1,842 rapes reported in 1985, compared to 14,449 in 2005. There may be a good explanation for this trend. Research by feminist scholars Hanmer and Saunders (1984) cited in Goodey (2005) found that everyday reality of womens encounters of violence by men were not revealed in the BCS because the BCS is not designed to reveal such information. Therefore the number of rapes on females may not have increased during this period, but the number of reports to the police has increased. This suggests that rapes which may have occurred prior 1995 are only being reported to the police in the last decade. This may be due to the social construction of the police changing. There are more female officers now than previously which makes rape victims more willing to talk to female officers than male officers. Society has also changed in order to pr ovide more victim support for rape victims by establishing rape centres for victims. However, Hough (2004) stated in the Guardian newspaper that the BCS shows that the major types of crime have fallen dramatically since 1995, however, recorded crime has increased. This increase is due to the change in the way in which police count crime. In 1998 it was decided that victim reports of crimes will be recorded even if they are doubted. This may be an alternative reason to why there is an increase in rape crimes, as rape is hard to record without sufficient evidence. Reservations over data How accurate are the estimates? Unreported rape may feel that the government cannot do anything about it There are several reasons why the BCS self-completion modules are likely to underestimate the true level of sexual victimisation in England and Wales for women à ¢Ã¢â ¬Ã ¢ general survey errors associated with response, sampling and coverage in particular, the BCS does cover institutions, the homeless or women under the age of 16, which excludes some high risk women à ¢Ã¢â ¬Ã ¢ the crime context of the BCS may lead to some women not reporting incidents they do not view as criminal, particularly where the perpetrator is known à ¢Ã¢â ¬Ã ¢ the screener question format will exclude women who do not identify with the particular terminology used in the questions à ¢Ã¢â ¬Ã ¢ the BCS interview is not always conducted in private and the presence of other people in the room may inhibit disclosure, especially if this includes the perpetrator of an attack. Conclusion actions and recommendations Sexual offence statistics could be improved by enhanced police procedures, and by having better facilities to encourage a greater willingness of victims to come forward. The sexual crime reduction team are committed to tackling sexual offences and to providing the right support for victims. Better facilities have been introduced through the introduction of 13 sexual assault referral centre across the country. The Government want to make these multi agency services for victims available on a national basis, along with a rape help line. Low reporting rates to the police particularly occur in the area of rape, where the respondent might find it embarrassing or difficult to talk about the attack. However, this problem is trying to be countered out. Computer assisted self-interview forms have been introduced for issues such as sexual attacks. Even so much of this area of offences is still missed as victims might want to stay in denial, and keep the fact that they have been a victim of a sexual assault within their sub-conscious, due to finding it to painful to think about. Further specialist training for sexual offence cases should be undertaken by officers. As a result of these services, victims should feel more confident from the outset that their case is treated with professionalism and empathy. In turn, it will improve theirs and others confidence in the criminal justice system. Ultimately, this enhanced approach should lead to more reporting, recording and subsequently more realistic statistics. Offer tips for rape prevention. Wider use of rape clinics, and awareness of these.

Gmos and Organic Food Essay
Why spend more money on organic food? Why are GMO products lasting longer? These are commonly asked questions which will be explained. By the definition of GMO products, they encompass alimentary products grown from seeds that have been genetically altered. Organic products are those that are grown under the traditional way, without any intervention of Bio-engineering, and also without the usage of chemicals, known as pesticides. The Author, Michael Pollan in both, ââ¬Å"Omnivoreââ¬â¢s Dilemmaâ⬠and ââ¬Å"In Defense of Foodâ⬠makes an extensive and detailed analyzation of the production of food now days. The big corporations (farms) are now known as manufacturing factories; where practically all the elements of their production process are strictly controlled. This highly technological system reduces the nutritional value of their products and in many cases their flavor as well, but it guarantees high volumes and longer shelf life of the products. An example of a food that would be known as a GMO would be tomatoes, which would be less healthy and again it wouldnââ¬â¢t taste the same as an organic one. Organic products are grown by small farmers according to old farming techniques. These products do not need the addition of micronutrients like GMOs; they maintain all the nutritional values and the original taste. Unfortunately, small farmers can not satisfy the demand that the market needs, let alone, the prices are higher. For example, if you were to sell organic tomatoes, you would have to need to sell them locally. If a company such as organic valley were to be ship organic products from California to New York, with them having shorter expiration date, they would end up going bad. It would be hard for everyone to have the budget to buy and eat organic food; even expensive restaurants donââ¬â¢t use organic food. So, what is better? Feeding a large growing population with GMO products; or to go back to square one, and run the risk of not having enough supply and have the prices skyrocket. At the end of the day, people will eat more GMO food for not everyone has money to buy organic food.

Artificial Heart Research: an Historical Perspective
Artificial Heart Research: An Historical Perspective (Rayan R. Joshi Third-year paper Food and Drug Law Advisor: Peter Barton Hutt) Good reasons for artificial hearts: * There are not enough heart donors (ââ¬Å"Each year, about 30,000patients are deemed eligible candidates for heart transplantation. However, only a small fraction of this group, numbering about 2000, actually winds up receiving donor hearts. Given the current figures, it is unlikely that the supply of donor hearts will increase enough to render all transplantation a viable means of combating end-stage heart disease on a macro level. ) Public opinions * Dr. Cooley believed that focusing the public's attention on the technology's future potential would have a positive effect on the field of research as a whole.* However, Cooley had grossly miscalculated in the realm of public opinion * Confronted with the gruesome images of a suffering human patient, society at large began to regard the entire held of artificial heart technology as ââ¬Å"more monstrous than miraculous,â⬠and research efforts in this area were quelled to a substantial degree. Nevertheless, given the state of the economy in the 80ââ¬â¢s, and the aversion towards this area of research held by many members of society, the Jarvik team ( a team working on designing a artificial heart) was strapped for much needed funding. * The extremely large amount of media coverage provided to the Clark operation proved to be a double-edged sword for researchers in this area.While the press' love affair with Clark's story initially focused public attention on the amazing potential benefits of heart research, the vivid and disturbing images of Clark's suffering after his operation shifted public opinion squarely in the opposite direction. Commentators who had once championed the efforts of ambitious heart surgeons now openly questioned whether it was appropriate for human physicians to be ââ¬Å"playing Godâ⬠in this area. If society we re to somehow lose interest in the potential benefits of MCSS technology, then researchers in this area would lose access to the public and private funding that they desperately need in order to ensure continued advancement. * The scientific import of the heart, combined with its cultural significance, renders heart research a particularly sensitive area in which to pursue the betterment of society. Nevertheless, pioneers with the courage to plow forward in this field over the last half century have saved countless lives as a result of their unwavering efforts.One thing, however, remains clear. If society is ever to reap the full rewards offered by MCSS technology, it will have to recalibrate its attitudes regarding the field in a more open-minded direction, one that hinges less on short term success, and more on long-term progress. Heroic patients like Barney Clark have accepted this challenge. Time will tell if society at large is capable of doing the same. There are two main bran ches of heart technology. Partial Artificial hearts: Partial devices supplement patients' natural heart function, assisting those patients whose organs, while somewhat viable, are incapable of functioning adequately on their own Total artificial hearts: ( we should focus on this !! ) * Total artificial hearts (TAH), on the other hand, are devices that actually replace patients' natural hearts. Such devices are designed for situations in which natural organs are so damaged that even supplementation via a partial device isn't enough to produce sufficient circulatory function.Collectively, partial and total artificial heart devices are classified as mechanical circulatory support systems (MCSS). 3 ways these technologies help 1 First, devices can serve asââ¬Å"bridgesâ⬠to transplant, allowing patients' conditions to stabilize while they await the delivery of donorhearts. 2 Second, partial devices can be used, either temporarily or permanently, to allow a patient's natural heart to rest and recover following periods of distress. 3 Finally, TAH devices can potentially serve as permanent replacements for those patients whose natural hearts are too damaged to permit recovery through alternative means.Replacement TAH devices represent the cutting edge of technology in this field. Rules and regulations * Artificial heart technology is subject to FDA regulation under the Federal Food, Drug, and Cosmetic Act of 1938 (Actâ⬠). * The Medical Device Amendments of 1976 (Amendmentsâ⬠) to the Act establish three regula- * tory classes for medical devices, ased on the degree of control necessary to assure that the various types of * devices are safe and e ective. â⬠* Artificial heart devices are considered part of Class III, and are thus subject to the heaviest possible regulation. A Class III device is defied in the Amendments as one that supports or sustains human life or is of substantial importance in preventing impairment of human health or presents a potential, unreasonable risk of illness or injury. * Class III medical devices may not be marketed by firms until the FDA has approved a pre-market approval (PMA) application under Section 515 of the Act. Dr. Michael E. DeBakey- a prominent surgeon at the Baylor College of Medicine in Houston * His research interests led him to form a team whose purpose was to explore the feasibility of building an artificial device that could replace the natural human heart.The history of total artificial hearts 60ââ¬â¢s * The development of total artificial heart technology can be traced to the early 1960's. * Indeed, by 1965, * a federal artificial heart program had been created, and its enabling legislation asserted that the program's * The visions of Cooley and Liotta came to fruition on April 4, 1969. That day, Cooley implanted an artificial heart into the chest cavity of 47 year old Haskell Karp of Skokie, Illinois, a printing estimator with a long history of heart related problems. Karp died from an infection and related complications shortly after having the operation* In response to the relative failure of the Karp experiment, stunted for more than a decade. 70ââ¬â¢s * by 1971, Dr. DeBakey himself became convinced that existing total artificial heart technology could not overcome the hurdles intrinsic within the human body. DeBakey was primarily concerned with two major problems. * First, scientists had to develop a power source that could be totally implantable, in order to reduce the risk of infection that was created by tethering artificial devices to external sources through skin penetrating pumps. Second, researchers had to discover and refine a non-clotting surface for the parts of the pump that actually came into contact with blood. Otherwise, the associated risk of stroke in patients would remain too high to warrant use of the technology. DeBakey ultimately determined that his time was better spent pursuing alternative avenues of heart research, asser ting ââ¬Å"I decided to stop putting my energies and efforts into a total artificial heart. â⬠80ââ¬â¢s *In the early 1980's a new figure named Dr. Robert Jarvik embarked on the quest for a well-functioning total artificial heart. The Jarvik-7 ( his design of a artificial heart) was a total heart that completely replaced the natural organ within the body's chest cavity * On December 2, 1982, a patient, Barney Clark received a Jarvik-7 implant in Salt Lake City. * Barney Clark was able to survive 112 days with the device however it came with a lot of complications. His blood kept clotting as it went through the heart which caused several strokes. * The artificial heart also had technological malfunctioning * The Jarvik-7 was implanted in a second patient, 53 year-old William Schroeder, at the Humana Heart Institute in Louisville, Kentucky. Schroeder actually survived on the device for 18 months.* Like Clark, however, Schroeder was plagued by multiple strokes, infections, and hemorrhages throughout the course of his treatment. * When asked directly for his opinion about the Jarvik-7, Schroeder made a horrible gesture, like he'd like to kill it or strangle it. * After Schroeder's death, public sentiment against artificial heart research reached alarming levels. * In response, FDA effectively revoked the IDE granted to the Jarvik-7 program. * Most researchers now became convinced, as DeBakey had a decade earlier, that the quest for an effective total rtificial heart was simply a fruitless endeavor. * . As a result of these forces, researchers and surgeons now began to bolster their efforts at finding alternative ways to combat heart disease 90ââ¬â¢s * As doctors becamemore adept at using anticoagulant drugs to reduce the risk of stroke associated with these transplants, the success rate of the device continued to improve. * Indeed, since 1993, 147 patients have been supported by Jarvik's original artificial heart, and 88 of these patients ultimately su rvived till their scheduled organ transplantsThe non-pulsatile LVAD * Dr. Richard Wampler, began to develop a non-pulsatile LVAD. Wampler was convinced that the body might not necessarily need a pulse to function effectively.
